The attaching made up of four bars ll, l2, l3 and I4, joined tomember is of a type adapted to fit overa supgether in any suitable manner to form substanporting structure such as a large chair and may tially a rectangle. This frame acts as a support for an apron l5 and also for a seat I, which is secured to the frame in a manner to be described in detail hereinafter. The apron ii may be pivotally mounted within the frame about an axis defined by the screws l1, so that it can be lifted out of the way of the occupant of the seat. A pair of stop members l8 fastened in the frame members l2 and I4 limit the pivotal movement of the apron and provide rests to hold the same substantially in horizontal position.

The seat I6 is made up preferably of wood having its side edges rounded as indicated at 2|. The seat It is secured to the frame of the chair by means of a pair of similar hangers 2|, pref erably made of metal and shaped as shown in the drawings, that is, with a double bend 22 at one end and a single bend 23 at the other end. The curvature of the bend 23 corresponds closely to the curvature 20 of the seat edges so that a pivotal movement of the hangers 20 about'the seat can be carried out. The double bend 22 is of such shape as to permit engagement thereof about the side bars l2 and I4 of the frame. The hangers are secured to the seat l6 by means of spaced pairs of screws 24 which pass through slots 25 in the ends of the hangers having the bends 23. These slots 25 are of such length as to permit the hangers to remain in the position shown in full lines in Fig. 4, or in the position shown in broken lines in the same figure.

Extending through the side bars l2 and I4 are spaced pairs of guide members 26 which are in the nature of bolts having heads 27 spaced from the inner surfaces of the side bars. The hangers 2| are provided with slots 28 which are of slightly greater width than the diameter of the bolts 26. The slots 28 have substantially vertical portions near the ends thereof with inclined portions between the vertical portions as shown olearly in Fig. 3. The purpose of these inclined cam slots will be explained hereinafter.

Secured to each hanger 2| is a side member 30, preferably made of wood, which members serve the purpose of preventing contact between the body of one seated in the chair and the metal hangers 2|. These side pieces 30 are provided with recesses 3| which are cut in the surfaces resting against the hangers 2| and which correspend in configuration to the slots 28. The recesses 3|, however, are wider than the slots 28 and are'of such depth as to receive. the heads 21 of the bolts 26.

Secured to the frame member l3 are a pair of angle bars 35 made of metal, and having extending upwardly therefrom studs 26 shown clearly in Fig. 7. The studs 36 are spaced a slight distance from the top of the angle of the bars so that slotted members 31 can be engaged with the connecting part of the stud. The members 31 are substantially Z-shaped, and are provided with slots 38which extend a part of the length of the intermediate portion of the members and into one toe portion thereof. The other toe portion of each member is provided with a slot 39 which permits the passage therethrough of bolts. As shown in Fig. 1, the members 31 have secured thereto a complementary member 40 which is slotted as shown, the members 31 and 40 being secured together by bolts and wing nuts 4|. -The slots 39 in the members and the slots in the member 4!) permit adjustment of the composite attaching member to adapt it to different conditions.

The exerciser of the present invention consists of three rods 45 which are pivotally seemed to the some cases each rod might be provided with a spring. An apron l5 may be provided with a central aperture 5| into which may be placed a dish 52'. The seat l6 may be provided with an aperture 52 in which can be located a commode,

53. Clips 54 secured to the underside of the seat l6 aid in retaining the commode into position.

I A cover 55 formed of the same material as the seat, is hingedly secured thereto as indicated at 56 for closing the aperture 52 when the commode is not in use.

A strap 51 has one end fastened to the seat It and the other end removably fastened to the underside of the apron ii for aiding in retaining an infant in the chair.

By inspection of the drawings, it will be observed that the inner edge of the apron I5 is shaped so that the mid portion thereof is curved inwardly as at 58, while the outer edge of the seat I6 is shaped in corresponding fashion, that is, with an outwardly curved part 59 and receding curved parts 60. Since both the apron and the seat are made of wood, it will be evident that the two parts of the chair may be cut from a single piece of material since the curvature of the apron corresponds exactly to the curvature of the seat. By having these curvatures correspond, the seat and apron can be cut from a piece of material by one cutting operation with the resultant decrease in waste of material.

The device is so arranged as to be capable of being collapsed into the position shown in Fig- I ures 5 and 6, or to be expanded into the position shown in Figures 1 to 3. When the device is expanded, the seat may be held against rocking motion'by means of sliding lock 65, which engages in a recess 66 cut in one of the double bends 22 of a hanger 2|.

The device when expanded assumes the position shown in the drawings and when in this position it may be attached to any suitable supporting member such as a chair 10. The method of attachment is very simple, since it is only necessary to engage the composite attaching member over the back of the chair as shown in Figure 1. Adjustment may be made of the composite attaching member to insure that the frame does not rock but is held in a substantially horizontal position. When the chair is attached to a supporting member such as a larger chair, it will be apparent that the seat l6 depends from the frame, being supportedby the hangers 2| which have parts folded over the side bars l2 and H. In this position the rear edge 12 of the seat I6 is substantially in line with the rear surface of the bar l3. Since the limits of the bar l3 and the side 12 are in substantially vertical alignment,

it will be apparent that the seat will press against the back of the chair 10 so it is not necessary to provide a separate back for the small chair. As before stated, tilting of the seat i6 is substantially prevented by the movement of the lock 65.

When it is desired to collapse the chair, the seat ii is pushed upwardly toward the frame of the device, which upward motion results in a sliding movement of the hangers 2| upwardly disengaging their parts 22 from the side bars l2 and I4. As these hangers 2| are forced upwardly their movement is slightly forward due to the inclination of the cam slots 28. During this movement of the hangers, the seat l6 approaches the frame with a rectilinear movement. Since the cam slots 28 extend downwardly into the bend 23 of the hangers, it is possible to move the seat I8 upwardly into the actual confines of the frame. When the seat has been moved upwardly into the position shown in Figures 5 and 6, the hangers can be rotated inwardly through an angle of approximately 90 degrees. This is made possible by the extended cam slots 28 and by the slots 28 which engage the guide members 24 on the seat. When the hangers have been folded through approximately 90 degrees, they assume the positions shown in Figures 5 and 6, in which it will be seen that the side pieces 38 lie flat against the top of the seat It. The exerciser may then be folded rearwardly until the bar 48 and the ends of the rods 45 lie against or adjacent the underside of the seat It. When the parts have assumed this position, they may be locked therein by movement of the composite attaching part from the position shown in Figure 3 to that shown in Figure 5, the slots 38 in the member 81 permitting such movement. If desired, the attaching part can be clamped to hold the parts in placed position quite clearly by a simple adjustment through the agen y of the bolts and wing nuts 4|.

- In this position the chair occupies a very small space, that is, a space only a slight bit greater than the over-all dimensions of the frame. For this reason the device is capable for ready transportation, and since it can be set up with a minimum number of motions, it adapts itself to a great number of uses.

When it is desired to attach the chair to a supporting structure the following steps may be carried out. The composite attaching member is moved out of locking engagement with the exerciser and other parts and is turned into the position shown in Figure 3. The exerciser is then free to swing downwardly. The seat may next be lowered into the position shown in Figures 1 and 3 by simply rotating the hangers 2| through approximately 90 degrees from the position shown in Figure 6. The seat is pushed downwardly until the bends 22 of the hangers engage over the bars l2 and I4. If desired, the apron l5 can be rotated upwardly so that an occupant 'can be seated in the chair more easily. Once the occupant is seated, the apron can be held against upward movement by attaching one end of the strap 51 to the underside thereof.

In some instances it may be desired to make use of a diiferent attaching part for attaching the chairs to objects of different configurations. To facilitate the removal of the composite at taching member, the slots 38 in the members 31 may be provided with a T-head as at 39' (Figure 7) which will permit disengagement of both members necting the part 48 from the parts 31. When the composite attaching members have been re-' moved, one of any desired shape can be secured to a chair in a similar manner to adapt the chair for use in connection with the back of an automobile'seat or other desirable locations.

A simple form of attaching member is shown in Figures 8 and 9 wherein angle bars 35 secured" to the bar I8 of the frame are provided with 31 from the studs 36 without disconupstanding portions 88 and curved over parts 8|. The upstanding portions are provided with slots 82 through which pass parts of a heavy wire 8-4 shaped as shown to provide an attaching mem- I her. The ends of the wire 84 are bent to flt under the curved part 8| of the angle bars when the device is used to attach the chair to a supporting member. When the chair is collapsed, the ends of the wire 84 are pressed downwardly to the lower extremity of slots 82 after which the entire attaching member can be turned through an angle of approximately degrees and then moved inwardly to retain parts of the chair in collapsed position. In Figure 9 the broken lines indicate the position of the wire when the device is ready for attachment to a supporting member while the solid lines indicate the position of the attaching member just prior to its inward motion to locking position.

In Figures 10 and 11, a slightly modified form of the invention is shown. The parts thereof which correspond to parts in the previously described embodiment of the invention are given similar reference characters with an addition of a prime to each thereof. The slots 28' are substantially vertical throughout their entire length as distinguished from the inclined slots 28 before described. As a result of this change in cam slot design, the seat l8 will move toward and away from the frame of the chair without any forward or backward movement. This device has as an additional element a back member which is made up of a metal hanger 98 somewhat similar to the hangers 2|, being secured to the rear edge of the seat l8 by means of guide screws 9| fitting in slots in the hanger. The slots in the hanger 90 correspond closely to the slots 25 shown in Figure 4. Thus it will be seen that the hanger 98 has a portion 92 which when the device is expanded fits under the seat It to aid in supporting the same. As integral parts of the hanger 98, a pair of ears v98 are pressed therefrom to extend rearwardly from the hanger as shown in Figure 11 and to lie substantially in the same plane as the part 92. These ears 93 are adjacent each end of the hanger and are connected by a bar 94 which may engage an upright member and hold the seat I6 away from such upright member. Thetop part of the hanger 90 is provided with a double bend 95 for engagement over the bar i3 of the chair frame. A back member 98 similar to the side members 80 is secured to the metal hanger 90.

When it is desired to collapse the chair in this form, the seat is raised upwardly until the double bond 95 and the double bends 22' are disengaged Due to the positioning of this hanger 9D, the side pieces 30' under ordinary circumstances will not lie flat on top of the seat l6 as in the previous embodiment but will be spaced a distance therefrom approximately equal to the combined thickness of the hanger 90 and the back piece 96. This is made possible by providing each hanger 2|" with a relatively long portion extending under the seat IS in expanded position with correspondingly longer slots through which pass the guide members 24'. A pair of spaced recesses are provided in the frame bar I8 for the reception of "the heads 9| ofthe attaching members for the of the invention.

The operation and use of this form of chair are similar to the operation and use hereinbefore described, the only differences being that the relative movement between the frame and the seat is strictly rectilinear Without the inclusion of any backward or forward motion, and in addition the back member has been provided to supply a positive support for the back of the occupant. In this form of chair reliance is not placed upon contacting between the rear edge of the seat and a supporting member such as a larger chair, since the connecting bar 94 between the cars 93 serves to hold the seat away from a supporting upright which is indicated in broken lines in Fig. 11.

A further modification of the invention is shown in Figures 12 to 14, inclusive. This form consists of a substantially U-shaped frame I00 made preferably of metal tubing of sufficient strength to withstand the stresses applied thereto. Depending from the arms of the frame I00 are two metallic hangers IOI which are secured to the arms by means of integral portions I02 rolled therearound. These portions I02 may have sliding fits with the arms of the frame. Intermediate the horizontal edges of the hangers IOI are spaced vertical slots I03. A seat I04 similar in shape to seats I6 and I6 is provided. The width of the seat I04 is approximately equal to or slightly less than the distance between the inner'surface of the rolled parts I02 of the hangers so that the seat can be moved into position to lie between the arms of the frame.

The seat is attached to the hangers IN by means of a plurality of metallic members I05 secured in the underside of the seat and then bent to expand horizontally from the edges thereof. The horizontal parts of the members I05 are spaced from the underside of the seat at a distance at least as great as the width of the hangers I0 I. These members I05 extend through the-slots I03 and are provided with loops I06 in the ends thereof to prevent disengagement of the hangers from the seat.

This form of chair is also provided with a back I 01 in the nature of a sheet of metal, which back is pivotally secured to the top side of the seat by means of an integral part I08 rolled around a bracket I09, the ends of which are embedded in the seat. The top part of the back I01 tapers off to 9. rolled part I I0 shaped to fit over the frame I00 as shown in the drawings. Extending outwardly from the lower edge of theback I01 and spaced from each end of rolled part I08, are integral spacers I I I which serve to hold the seat in spaced relation to a vertical support when the chair is expanded and attached to such vertical support.

Rigidly secured to the back part of the frame I00 are brackets I I5 which have vertical portions H6 and rolled tops Ill. These brackets are provided with slots in their portions H6 and in part of their rolled tops III. Through these slots extend the ends of a wire attaching member I I0, the ends being bent under as indicated at I I0 to prevent disengagement of the attaching member H8 from the brackets. This attaching member, due to these slots, can be rotated and then can be pressed inwardly to hold the parts of the chair in collapsed position.

An apron I20 preferably of wood is secured to the arms of the frame I00 by means of a sleeve I2I on one edge thereof which encircles an arm of the frame and a partial sleeve I22 at the other edge thereof, which can rest on the other arm. By this arrangement of total and partial sleeves, it is possible to swing the apron upwardly about one of the arms as a fulcrum, or to slide the apron toward or away from the back of the chair.

The expanded position of a chair is shown in Figure 12 in which the seat I04 is supported by the hangers IOI due to the engagement of the member I05 in the slots I03. The back I01 has its rolled portion H0 in engagement with the back part of the frame I 00. In this position the chair may be suspended from any upright object by merely placing the attaching member I I8 over this object. The spacers I I I are provided to rest against the upright object or a separate upright object, and due to the sliding arrangement of the hangers IOI relative to the arms, it is possible to move the seat forwardly or backwardly a slight amount to permit adjustment thereof.

When it is desired to collapse the chair the seat is raised upwardly, which upward movement automatically disengages the rolled part IIO of the back from the frame after which the back may be folded to lie flat against-the top of the seat. As the seat is pushed upwardly, the hangers are drawn inwardly progressively as shown by broken lines of Figure 14 until the seat lies entirely within the confines of the frame. The hangers IOI can be folded under the seat with parts thereof in the space between the bottom of the seat and the members I05. The attaching member H8 may be swung around into position to hold the parts in this collapsed relation.

If desired, a strap I22 can be used as in the previous embodiment of the invention, and also an exerciser similar to that already described can be attached to the underside of the seat I04.

While the chair of Figures 12 and 14 has been described specifically as one being suitable for infants and small children, it will be apparent that the use thereof is not so limited. The chair may be constructed on a larger scale, for example, of suflicient size to accommodate an adult and can be made use of at athletic events or on any other occasion wherein it is desirable to make use of temporary seating arrangements. Since the chairs can be collapsed into a relatively compact article, they can be transported very easily and can be set up in a minimum space of time. The only other equipment necessary for assembling a. number of these chairs consists of vertical supports of the proper character from which the chairs could be suspended.

In all of the forms of the invention described hereinbefore, a number of advantages are inherent. It is well known that babies orsmall children when placed in a chair like to have something upon which they can rest their feet with their legs substantially in horizontal position. It has been discovered that such practice is detrimental to the proper development to the children, and accordingly, this invention overcomes the objections just stated. By having the seat so shaped that the intermediate part of the front edge thereof is curved outwardly from receding curved parts, it becomes natural for the occupant to permit his legs to extend downwardly as shown in Figure 3. Furthermore, there a,ooa ,oeo is nothing in this construction upon whichthe occupant could rest his feet with his legs in a substantially horizontal position. Furthermore, the chair is so shaped as to assure correct posture of the occupant; In the form shown in Figures 1 to 6, inclusive, the seat when the device is expanded, moves rearwardly a slight amount to engage the upright supporting member, and the back of the occupant is actually supported by the rear bar IS. A separate back for the chair is not necessary in this form of the device. In the arrangement shown in Figures 10 and 11 the separate back is provided, which in someinstances may be desirable. The same is true of the embodiment shown in Figures 12 and 14.

From an inspection of the drawings, it will be seen that relative movement between the seat and frame is limited by the engagement of the top of the hangers over the arms in expanded position of the chair, and by contact of the seat with the guide studs in collapsed position of the chair, (Figs. 1 to 11). In the form shown in Figs. 12 to 14, the studs IOQ serve to limit such movement. 7

In all forms of the invention, the exerciser may be attached to the underside of the chair and when so attached it becomes natural for the occupant of the chair to rest his feet upon the bar 48. The natural tendency would be to press down upon this bar, but due to the springs 49 such pressure is yieldingly resistant. Children, however, will continually press down upon the exerciser with the result that the repeated up and down movement of the legs and the feet will exercise such membersvery beneficially. Moreover, since the foot will engage the bar 48 approximately at the instep thereof the repeated application of pressure will very materially aid in exercising the instep of the occupant.

In the event it should be desired to convert the chair into a swing, chains or cords can be at-' tached to eye screws I30 (Figure 2) for suspending the chair in any desired position.
